Attending Jamie Oliver's Instagram party held at Piccadilly hotspot Barbeco, Stephanie and Josh enjoyed a fun-filled evening out alongside the likes of TOWIE's Lauren Pope, Laura Whitmore and One Direction's Liam Payne.
For the showbiz bash, Stephanie looked gorgeous in her girly getup. The former Hills star looked beautifully bronzed, choosing to bare her enviable pins in a pleated mini-skirt.
She teamed her skirt with a white-collared shirt, a cute slogan jumper and a leather jacket to keep off the chill. To finish her outfit, Steph wore a gorgeous pair of Saint Laurent boots with silver chain detailing, sporting glossy lips and perfectly blow-dried locks.
On her arm, boyfriend Josh kept things casual in a checked shirt and dark-wash jeans.
The couple's outing together comes after Steph and Josh's relationship recently reached the six-month mark.
To mark the milestone, Steph shared a photo of herself with her beau, telling Josh: "I love you more and more every minute."
Returning the favour, the Chelsea boy too posted a photo of the pair to Instagram. Alongside his snap, Josh said: "6 months with this dream. @officialstephpratt."
The couple first began dating last year, after Josh joined the cast of Made In Chelsea. And while their romance hasn't been completely drama free - there were a few tense moments between the pair and Stevie Johnson (Steph's former flame and Josh's best friend) - the pair are still very much loved-up.
Stephanie and Josh are now even living together in Chelsea, and it seems the blonde beauty is loving every minute.
Taking to Twitter last night, Stephanie told fans: "Driving past the London Eye & Big Ben... It really never sinks in that I live in such an incredible city!! I love you London #grateful."
Made In Chelsea is set to return to our screens later this year.
